ORE-PULVERIZING MACHINE.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed May 31, 1910. Serial No. 564,324.

To all whom it may concern:

Be it known that I, MATTHEW ARNOLD, a citizen of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented a new and useful Improvement in Ore-Pulveriziug Machines, of which the following is a specification.

It is the object of my invention to so construct an ore pulverizing machine that it may be formed of sufiiciently strong material and parts hardened in such a manner to resist the wear of the pulverizing zone to a very small percentage, and also producing pulverized ore of any grain that may be required through the proper adjustment of said machine,- and saving more gold, and doing twice the work, with less power and less water than in the old way with stamp mills.

My machine is so constructed that any wear that comes to any part is automatically taken up.

The ore before being fed to this machine is first crushed to the size required.

The capacity of the machine can be i11 in the length of the stroke.

In reference to the drawings: Figure 1 if a sectional side elevation and Fig. 2 is transverse sectional view. 4

Referring to the drawings L is a movable frame or carriage with which the pulveriz-l, in'g wheel, the hoppers, the ore feed chutes water pipes, etc., move back and forth.

B is the main frame and support of my pulverizing machine.

. The pulverizing wheel C is made of'the hardest and finest carbon, steel, and moves back and forth on bar A as frame or carriage L tpasses backward and forward. It passes o of said bar at each end thereof at the end of each stroke so that the wear of the bar will be distributed equally over its entire length.

C are the roller bearings of wheel C. These roller bearings are made of steel, the proper size and length and hardened and are placed between the two inner circles of wheel C to lessen the friction on wheel C, when the same is at work. Wheel C revolves upon these roller bearings in either direction. I is the main driving shaft and extends through frame B. This shaft is square. There is a pinion A, fitted on shaft 1. The pinion A is held constantly in mesh with gear A by a yoke bearing A attached to frameL, and is shown in dotted lines hehind gears A and A. Pinion A engages and drives bevel gear A on shaft running through wheel C. The bevel gear on the other d of the last mentioned shaft engages nd drives the bevel gear E at one end of shaft 1". At the other end of shaft E a pi ion P is attached which works in rack P fastened to frame B.

Belts on pulleys Z drive gear Z which engage and drives gear Z attached at one end of Ynain shaft I.

Z are two loose and one tight pulley, and the belts driving the same are one cross and one strhight belt. The belts on pulleys Z are shifted by a shift rod, not shown, coming in cont ict with frame L at the end of each stroke; and the direction of movement of frame J is thereby reversed.

It e the bearings of main shaft 1. The springs on main shaft 1, shown at R Fig. 1, are for the purpose of cushioning frame L at the end of each stroke, and also for the purpose of lessening the friction on shift belts at Z. The weight of frame L is held up to frame B by springs shown at B. The rollers, shown at B Fig. 2, are attached to frame L and roll on top of'frame B taking the weight of frame L while wheel C is off of bar A at the end of the stroke.

The roller bearings B" are attached to frame L and bear against frame B. They take the upward strain of frame L. A is a longitudinal bar, made of the hardest and finest carbon steel. This bar is the pulverizing track, or surface, and rests u on and is supported by a heavy beam or b ock A Block A is set in and supported by frame B. There is a portion of frame B, corresponding in width with bar A, which extends from each end .of frame B centrally, and buts up against the ends of block A and prevents the block A from being displaced'at either end. The to of this portion is slightly lower than he 11 per surface of bar A. To this portion 0 frame B the levers S hereinafter described, are fulcrumed, andthe stop pins E are also set therein. M are one quarter circle arms, one

on each side of wheel :0, shown at Fig. 1,

and are attached to frame L, one on each end thereof, by fulcrum pins N.

The up er ends of arms M are attached to one end of a rod which runs through a guide attached to frame L. There is a nut on the 7 other end of said rod, and onsaid rod, between said guide and said nut a spiral spring 0 is placed for the purpose of adjusting quarter circle arm M. At the lower extremity of arm M is a wheel, shown at 6, which bears against the flanges on either side of wheel C, holding up the weight, and taking up the lost motion of wheel C while off of bar A. 'E are the ore hoppers, attached to frame L. The ore is fed from hoppers E through sleeve chutes D on to bar A, in front of advancing wheel C by gravitation. Chutes D are adjustable and can be raised the exact distance from bar A-as to corre spond with the depth of ore desired to be fed on bar A, and the ore is laid on said bar, and leveled by the bottom of sleeve chutes D asframe'L passes forward. There are two ore chutes, one on each side of wheel C, and while the onein front of the advancing wheel is open the other is closed.

The chutes are closed and opened as follows The sliding lever E is provided with a projection, running upward, and this projection comes in contact with a pin on shut gate F in front of the advancing wheel, just as the chute reaches the end of bar A, and closes the gate, and lever E? passing forward has reached the topof shift arm S v and has pushed the same over, and the arm of S shown at Fig. 1, extending centrally at an angle from S is raised and strikes the pin on the gate on the other side of wheel C as, the motion of frame L is reversed and opens the gate. As lever E leaves the arm S on the reverse motion of frame L the,

balance weight Bl/V, on cord E shown passing around rollers E and attached to the lower end of shift arm S at E brings a shift arm S and the lever thereof back to place and in contact with stop pin E set inframe B. Lever E is attached to frame L and travels back and forth therewith.

The balance weights, shown at H attached to a cord' passing over sheaves, shown at H hold up sleeve chutes D While wheel C is off of bar A. J are guides, connected to r frame L, one on each side of wheel 0, and

pass back and forth with wheel G holding the ore in place, and. preventing any ore or dust from escaping from bar A at this'pointbetween wheel Cand ore chutes D. These said sleeves.

pipes are attached to frame L and move back and forth therewith. Water is supplied to pipes G by telescope pipes G fastened to frame L and fulcrumed at the bottom of frame B at G lengthening and shortening .with the mot-ion of frame L.

G are valves which are opened and shut by rack and pinion, shown at G, constructed in such a manner as to close the valve in or washouts from frame B, and they open into chutes H.

g X is a shaft at the lower part of frame and runs therethrough. Attached to thls shaft are the spiral gears SA connect-ing screws Y, the gears SB, and the clutches V.

A clutch V is attachedat each end of shaft X id passing upward from these clutches are-"springs T which work in a sleeve, and

at the top of these sleeves are bevel arms,

as shown at S, Fig. 1, lying in the jaw of frame L, and at the lower part thereof, pass with the movement of frame L onto the.

bevel arms S and press down on springs T and lock clutch V as wheel G leaves bar A. This prevents the turning of shaft X.

jShaft X in turning turns-the spiral gears SA which are connected to screws pose of raising bar A, resting on block 'A to. the proper position for pulverizing, also Rollers W at both ends ofto take up any wear of thepulVeriZing sur- 7 face. The clutches V are locked while wheel C is off of bar A for. the apparent reason that the resistance of the weight of frame L, wheel C, etc, is then off bar A, at which time the balance weight and cord BWpassing over sheaves X would turn-the drum SS, thereby turning the gears SB, and the shaft X, and the screws Y, thus raising bar A beyond the proper point if the turning of the shaft was not checked by means of locking clutches V. Arms S are fulcrumed to frameB at their larger ends, and are supported midway of their length upon the tops of shafts 8 of clutch V, andwhen roller W, on the reverse motion, leaves arms S wheel G is back on bar A and the.

weight thereof is off of spring T, andthe clutch V is released. The balance weight on cord BW turns the drum SS thereby turn ing the ears SB on shaft X, and the screws Y raise ar A to the adjusted point for the gram of ore desired. Bar A is adjusted by means of an adjustable stop X on balance weight cord BlV, at the proper place thereon, coming in contact with a bracket X shown at Fig. 1, thereby arresting and holding the weight on cord and preventing the further turning of screws Y.

The wear of shaft I is taken u by balance weight 13W and balance weight BlV at opposite ends of frame B. The cords attached to these weights pass over sheaves X and are secured to bearings It, as shown at Fig. 1.
